Lab: Gas Laws Purpose: Obtain a reference of temperatures effect on gas using Charles’ law when heating a capillary tube in water on a heated hot plate. Then‚ cooling the same capillary tube with ice while measuring the temperatures cooling effect on the gas bubble inside the capillary tube. Measurements of temperature change are taken with microLAB sensor and graphed using microLAB software. A final determination of experiments determined absolute zero versus actual absolute zero will be

Introduction: The goal of this experiment was to measure the amount of gas produced in various reactions. The Ideal Gas Law was needed in order to calculate the mass of reactants and moles of gas produced: ‚ where is the pressure in atm‚ is the volume in Liters‚ is the number of moles‚ is the ideal gas constant [0.082 (Latm)/(Kmol)]‚ and is the temperature in Kelvins. Considering the units on R‚ it was important to convert pressure‚ volume‚ and temperature to atm‚ L‚ and K‚ respectively. In

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical

The Ideal Gas Law Lab taught me that hydrogen is lighter than air‚ and can be ignited. The materials used for the experiment include 0.05 grams of magnesium‚ 1M H2SO4‚ water‚ a 100mL graduated cylinder‚ and a beaker. The hydrogen can be ignited with a match. First‚ the beaker is filled with water. The acid is then added to the graduated cylinder‚ with about ¾ inch left at the top‚ which is space for water. Afterward‚ the magnesium is added to the graduated cylinder‚ and it is inverted upside down

Reading the “Dumpster Diving” essay put me in the perspective that we throw away a lot of different things that may seem like junk or trash to us. However‚ “one man’s trash is another man’s treasure‚” and what may be trash to us is the way of life for someone else . Lars Eighner describes his experience in dumpster diving‚ and while doing so‚ he makes a comment in the essay to say he would prefer to call dumpster diver “scavenging.” Eighner writes this essay to tell everyone about his years he

characteristics are true in some cases‚ but in others it’s just a way of stereotyping people‚ like the notion that blonde girls are dumb or Asians are bad drivers. In the two articles “On Dumpster Diving” by Lars Eighner and “The Lady in Red” by Richard Lemieux‚ Eighner provides for himself free of cost by dumpster diving‚ but Lemieux is simply at what most people would call “rock bottom” of his life at the time‚ so he resorts to begging people for money. These two men are not your typical drunk bums hanging

On Dumpster Diving” Who throws away the best stuff? Is dumpster diving really necessary to people living on the streets? In the text book‚ Lars Eighner‚ “On Dumpster Diving”‚ tells about when he was homeless out on the streets.
